I've used the following command to replace the original copyright header
lines in a C-style comment block:
```
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f -exec perl -pi -e 's{/\*[^*]*\(\s*c\s*\)\s*(\d{4})\s*Icinga\s+GmbH[^*]*\*/}{// SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n// SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +
```
For files that use shell-style comments (#) like CMakeLists.txt, I've
used this command:
```
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f -exec perl -pi -e 's{#.*\(\s*c\s*\)\s(\d{4})\sIcinga\s+GmbH.*}{# SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n# SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +
```
And for SQL files:
```
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f \( -name '*.sql' \) -exec perl -pi -e 's{--.*\(c\)\s(\d{4})\sIcinga\sGmbH.*}{-- SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n-- SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f \( -name '*.sql' \) -exec perl -pi -e 's{-- Copyright \(c\)\s(\d{4})\sIcinga\s+Development\sTeam.*}{-- SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n-- SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +
